#Followthe instructions inthe serviceinterval displayregardingthe oilchange.
*NOTEDamagecausedbyaddingtoomuch engine oil
Too much engine oil can damagethe engineorthe catalytic converter.
#Haveexcess engine oilremoved at aqualified specialistworkshop.
#Turncap1counter-clockwise andremoveit.
#Add engine oil.
#Replace cap1and turn it clockwise asfaras it will go.
#Checkthe oil level again (→page 399).
Checking coolant level
&WARNINGRisk of burns from hot com‐ponent parts inthe engine compartment
Certain components inthe engine compart‐ment can beveryhot, e.g.the engine,theradiator and parts oftheexhaust system.
#Allowthe enginetocool down and onlytouch component parts described inthefollowing.
&WARNINGRisk of scalding from hotcoolant
The engine cooling system is pressurized,particularly whenthe engine iswarm. Ifyouopenthe cap,you could be scaldedbyhotcoolant spraying out.
#Letthe engine cool down before open‐ingthe cap.
#When openingthe cap,wear protectivegloves and safetyglasses.
#Openthe cap slowlytorelease pres‐sure.
Maintenance and care401

#Parkthevehicle on a level surface.
#Checkthe coolanttemperature display intheinstrument cluster.The coolanttemperature must be below158 °F (70 °C).
#If necessary,removethe cover.
#Slowly turn cap1counter-clockwisetorelieve overpressure.
#Continue turning cap1counter-clockwiseandremoveit.
The coolant level is correct:
RIfthe engine is cold, uptomarker bar2.
RIfthe engine iswarm, upto0.6 in (1.5 cm)over marker bar2.
#If necessary,add coolantthat has beenapprovedbyMercedes-Benz.RFurther information on coolant:(→page472)
Addingwasherfluidtothe windshieldwasher system
&WARNINGRisk of burns from hot com‐ponent parts inthe engine compartment
Certain component parts inthe engine com‐partment can beveryhot, e.g.the engine,the cooler and parts oftheexhaust system.
#Letthe engine cool down and onlytouchthe component parts describedasfollows.
&WARNINGDanger of burns when open‐ingthe hood
Ifyou openthe hood whenthe engine hasoverheated or during afireinthe enginecompartment,you could come into contactwith hotgases orother escaping operatingfluids.
#Before openingthe hood, allowtheenginetocool down.
#Intheevent of afireinthe engine com‐partment,keepthe hood closed andcallthefireservice.
&WARNING‑ Risk offireand injury fromwindshieldwasher concentrate
Windshieldwasher concentrate is highlyflammable. It could ignite if it comes intocontact withhot engine component parts ortheexhaust system.
#Make surethat no windshieldwasherconcentrate spills out nexttothefilleropening.
402Maintenance and care

Notes on cleaning and careAvoidingvehicle damage
Exterior lightingCleanthe lenses with awet sponge and mild cleaning agent,e.g. car shampoo.Only use cleaning agents or cleaning clothsthat are suitablefor plastic lenses.
SensorsCleanthe sensors inthe front andrear bumper and intheradiator grill with a soft clothand car shampoo.When using a powerwasher, maintain a minimum distance of11.8 in (30 cm).
Rear view cameraand360° CameraROpenthe camera cover withthe multimedia system(→page 231).
RUse cleanwater and a soft clothtocleanthe camera lens.
Do not use a powerwasher.
TailpipesClean with cleaning agentsrecommendedbyMercedes-Benz,particularlyinthe winter and afterwashingthevehicle.Do not use acidic cleaning agents.
Notes on care ofthe interior
&WARNINGRisk of injuryfrom plasticparts breaking off afterthe use of sol‐vent-based care products
Careand cleaning products containing sol‐vents can cause surfaces inthe cockpittobecome porous.
Whenthe airbags are deployed, plastic partsmay breakaway.
#Do not use any care or cleaning prod‐ucts containing solventstocleanthecockpit.
&WARNINGRisk of injuryor death frombleached seat belts
Bleaching or dyeing seat belts can severelyweakenthem.
This can,forexample, cause seat beltstotear orfail in an accident.
#Never bleachor dye seat belts.

Notes onstarting assistance and oncharg‐ingthe12V battery
Vehicles with a lithium-ion batteryWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
*NOTEDamagetothe battery fromover‐voltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthe on-board electronics may be damaged.
#Only use batterychargerswith a maxi‐mumchargingvoltage of14.4V.
AllothervehiclesWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
*NOTEDamagingthe batterythroughovervoltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthevehicle electronics may be damaged.
#Only use batterychargerswith a maxi‐mumchargingvoltage of14.8V.
&WARNINGRisk ofexplosion fromhydro‐gengas igniting
A batterygenerateshydrogengas duringthecharging process. Ifthere is a short circuit orsparksstarttoform,there is a danger ofthehydrogengas igniting.
#Make surethatthe positiveterminal ofthe connected battery does not comeinto contact withvehicle parts.
#Never place metal objects ortools on abattery.
#When connecting and disconnectingthebattery,you must observethe descri‐bed orderforthe battery clamps.
Breakdown assistance421

#When givingstarting assistance, alwaysmake surethatyou onlyconnect bat‐teryterminals with identical polarity.
#Duringstarting assistance,you mustobservethe described orderfor con‐necting and disconnectingthe jumpercables.
#Do not connect or disconnectthe bat‐teryclamps whilethe engine isrunning.
&WARNINGRisk ofexplosion duringcharging process andstarting assistance
Duringthecharging process andstartingassistance,the battery mayrelease anexplo‐sivegas mixture.
#Avoidfire, openflames, creating sparksand smoking.
#Make surethatthere is sufficientventi‐lation duringthecharging process andduringstarting assistance.
#Do not leanover a battery.
&WARNINGRisk ofexplosion from a fro‐zen battery
A discharged battery may freeze attempera‐tures slightly aboveor below freezing point.
Duringstarting assistance or batterycharg‐ing, batterygas may bereleased.
#Alwaysthawa frozen batteryoutfirstbeforecharging it or performingstart‐ing assistance.
Ifthe indicator/warning lamps inthe instrumentcluster do not light up at lowtemperatures, it isverylikelythatthe discharged battery has fro‐zen. Inthis caseyou may neither jump-startthevehicle norchargethe battery.
The service life of a batterythat has beenthawed may be dramatically shortened. Thestartingcharacteristics may be impaired, espe‐cially at lowtemperatures.
It isrecommendedthatyou haveathawed bat‐terychecked at aqualified specialistworkshop.

Whenthestarting assistance/charging processis complete:
#First,removethe jumper cable/chargingcable from ground point5and negativepole ofthe donor battery,then from positiveclamp4and positive pole ofthe donor bat‐
tery. Begin eachtime with the contacts onyourownvehiclefirst.
#Afterremovingthe jumper cable/chargingcable, close cover3of positive clamp4.

Replacing the12V battery
#Observethe notes onthe12V battery(→page419).
Mercedes-Benzrecommendsthatyou havethe12V batteryreplaced at aqualified specialistworkshop, e.g. at an authorized Mercedes-BenzCenter.
Observethefollowing notes ifyouwanttoreplacethe batteryyourself:
RAlwaysreplace afaulty batterywith a batterywhich meetsthe specificvehiclerequire‐ments.
Thevehicle is equipped with anAGMtechnol‐ogy battery (Absorbent Glass Mat) or a lith‐ium-ion battery.Fullvehicle functionality is
only guaranteed with anAGM battery or lith‐ium-ion battery.For safetyreasons,Mercedes-Benzrecommendsthatyou onlyuse batteries which havebeentested andapprovedforyourvehiclebyMercedes-Benz.
RCarryover detachable parts, such asventhoses, elbowfitting orterminal coversfromthe battery beingreplaced.
RMake surethatthevent hose is alwayscon‐nectedtothe original opening onthe side ofthe battery.
Install anyexisting or supplied cell caps.
Otherwise,gases or battery acid couldescape.
